Default schedule logstash (issue with indexing to Elasticsearch)

[malhotras (Samta Malhotra)]

I am facing problem with Indexing data to Elasticsearch using logstash. I noticed that Logstash is scheduled to restart changing process id after certain point of time. This is creating problem with indexing data to the Elasticsearch.

systemctl status logstash

I have no scheduling set-up in my logstash conf file. Is it happening by default?

 jdbc {
            jdbc_connection_string => "jdbc:informix-sqli://informix:1500/star:INFORMIXSERVER=test"
            jdbc_user => "star"
            jdbc_password => "****"
            jdbc_driver_library => "/etc/logstash/lib/ifxjdbc-3-50-JC7.jar"
            jdbc_driver_class => "com.informix.jdbc.IfxDriver"
            jdbc_fetch_size => "5000000"
            statment => "select * from start"
 }

Any suggestions??
